I am new to the MIDI protocol and I wonder why my Allen & Heath Xone K2 controller is detected and working (at least with some non-intuitive mapping) in Mixxx, while QLCPlus detects the device, but I cannot find a working configuration. Even the Channel Wizard remains blank even though the output of touched sliders is visible with aseqdump -p <port from aseqdump -l>
Is there something I have overlooked? (Arch Linux 6.2.9-arch1-1)
